## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-24.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 1077 tokens (~107/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 97/100
  - Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (10)

### `lookup_provision` (~120 tokens)

Lookup Provision

Look up a CFR provision by citation (e.g. "21 CFR 1304.04") or by an exact quotation, optionally as of a past date. Returns the provision text with a ProvisionEvidence object (source, snapshot date, hashes). Explicitly reports ambiguity or no-match instead of guessing. Requires a free API key.

Input parameters:

- `as_of` (string): Optional YYYY-MM-DD snapshot upper bound (not in the future)
- `q` (string, required): Citation ("21 CFR 1304.04") or an exact quote from regulatory text

### `get_provision_history` (~111 tokens)

Get Provision History

Documented change history for a CFR provision by canonical id (e.g. "21-cfr-1304.04(a)"): before/after text, computed redline, observed dates, and candidate final rules. 404 when the provision is not in the documented-change set — absence of a documented change is not a claim that nothing changed. No API key required.

Input parameters:

- `canonical_id` (string, required): Canonical provision id, e.g. "21-cfr-1304.04(a)"

### `rules_amending` (~176 tokens)

Rules Amending

Which final rules amend a CFR part or section, read from each rule's own amendatory instructions ("Amend § 52.2120 by..."). Returns the rules, the sections each addresses, and dates. This reports what a rule SAYS it amends — it is not an attribution of any observed text change to that rule. Covers 2020-present; absence means not indexed, not that no rule amended it. No API key required.

Input parameters:

- `limit` (integer): Max rules (default 50, max 200)
- `part` (string, required): CFR part, e.g. "52"
- `section` (string): Optional section id, e.g. "52.2120". Omit for all rules touching the part.
- `title` (string, required): CFR title number, e.g. "40"

### `recent_cfr_changes` (~51 tokens)

Recent Cfr Changes

Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required.

Input parameters:

- `limit` (integer): Max rows (default 50, max 200)

### `get_stats` (~28 tokens)

Get Stats

Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required.

### `search_regulations` (~98 tokens)

Search Regulations

Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key.

Input parameters:

- `limit` (integer): Max results (default 25, max 50)
- `page` (integer): Page number (default 1)
- `q` (string, required): Search query (min 3 chars)
- `tab` (string): Result type (default all)

### `list_rules` (~127 tokens)

List Rules

List Federal Register documents with filters: agency slug, document type, rulemaking pathway (interim_final/temporary/direct_final = notice-and-comment bypass classes), or docket id. Requires an API key.

Input parameters:

- `agency` (string): Agency slug, e.g. "environmental-protection-agency"
- `docket` (string): Docket id
- `limit` (integer): Max rows (default 25, max 100)
- `page` (integer): Page number (default 1)
- `pathway` (string): Rulemaking pathway
- `type` (string): Document type

### `list_obligations` (~118 tokens)

List Obligations

List extracted regulatory obligations ("who must do what") with filters: agency, deontic class, free text. Obligations are machine-extracted with quality tiers; they are not legal advice. Requires an API key.

Input parameters:

- `agency` (string): Agency slug
- `deontic` (string): Deontic class
- `limit` (integer): Max rows (default 25, max 100)
- `page` (integer): Page number (default 1)
- `q` (string): Full-text filter within obligations

### `get_requirement` (~38 tokens)

Get Requirement

Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key.

Input parameters:

- `id` (string, required): Requirement id

### `get_rule_comments` (~73 tokens)

Get Rule Comments

Public comments for a Federal Register document (organization, title, date, body where available). Coverage is partial and stated in the response. Requires an API key.

Input parameters:

- `doc` (string, required): Federal Register document number, e.g. "2024-12345"
- `offset` (integer): Row offset for pagination
